Powys Fadog

Powys Fadog was a Welsh princely realm that existed in northern Powys from 1160 to 1277, with Dinas Bran and Glyndyfrdwy serving as its historic capitals. In 1215, Powys Fadog decided to align itself against England, and it became a vassal of Prince Llywelyn ap Gruffudd in 1267. In 1276, Powys Fadog fell into a state of civil war, and the English invaded the country a year later and forced Madog II to submit to English rule.
